Formulae for determining the coordinates of points along a specified great circle path and for determining the times of sunset and sunrise at these points are given.A computer program for making the calculatio * ns and showing which portions of a great ci Topic: Ionosphere.
This report presents some results of work done with a Doppler technique for studying ionospheric disturbances. The theoretical results include a calculation of the frequency shifts to be expected from ch * anges in the parameters of a parabolic model iono Topics: Solar flares., Ionosphere.

An approximate theory for conversion of modes in an earth-ionosphere waveguide is propounded.The model is two concentric spherical reflecting boundaries which have prescribed surface impedances.The localized irregularity at either the ground or the ionosp Topics: VLF radio wave propagation., Wave guides., Lower ionosphere.
